DETAILED DESCRIPTION

It should be understood at the outset that although illustrative implementations of one or more embodiments are illustrated below, the disclosed systems and methods may be implemented using any number of techniques, whether currently known or not yet in existence. The disclosure should in no way be limited to the illustrative implementations, drawings, and techniques illustrated below, but may be modified within the scope of the appended claims along with their full scope of equivalents.

Embodiments of the disclosure are directed to methods and systems for completing and/or enabling secure online credit card transactions. In some cases the transactions may be completed using a mobile device, wherein the mobile device may communicate credit card information during a transaction. In some embodiments, a mobile device may access the Internet to complete an online transaction. In other embodiments, a mobile device may be enabled to communicate credit card information with a point of sale (POS) terminal via near field communication (NFC), wherein the mobile device and the point of sale terminal may be NFC-enabled. In yet other embodiments, a transaction may be completed using a device separate from the mobile device such as a computer, for example.

The use of proxy credit card information (created based on original credit card information) may provide protection for a user's original credit card information. For example, if the proxy credit card information is used in an online transaction and then the proxy credit card information is stolen, the original credit card information would be protected, and the usage rules associated with the proxy credit card information may prevent unwanted transactions from occurring. The use of the proxy credit card information may protect the user from losing (and therefore possibly having to cancel) their original credit card, and it may protect the issuer or network of the original credit card from unwanted transactions that the issuer or network may not be able to charge to the user. The use of the proxy credit card information may reduce the fraud exposure of the issuer, for example may limit the fraud exposure to a limited period of time, to a limited number of transactions, and/or to a limited number of merchants.

To provide security for transactions completed as described above, a mobile device may comprise an application operable to create the proxy credit card information based on original credit card information. There may exist a relationship between the proxy credit card information and the original credit card information, wherein the relationship may be recognizable by multiple parties such as the user and the issuer of the card. In an embodiment, a portion of the original credit card information may remain unchanged in the proxy credit card information. The original credit card information may, in some cases, be stored in a secure element within the mobile device, where the application may access the information stored in the secure element. The proxy credit card information may be communicated during a transaction so that the original credit card information is protected from theft or fraud. The proxy credit card information may be communicated to the issuer and/or network of the original credit card information so that transactions completed using proxy credit card information may be associated with the owner/user of the original credit card information.

In some cases, the proxy credit card information may be generated by an application on a mobile device and then communicated from the mobile device to a server/database of the issuer/network of the original credit card. Alternatively, the issuer/networker may receive indication from the mobile device that proxy credit card information has been generated and may also generate the proxy credit card information in a similar fashion as the application on the mobile device. By receiving and/or generating the proxy credit card information, the issuer/network may associate the proxy credit card information with the correct owner/user of the original credit card information. The proxy credit card information may be generated (by the mobile device and/or the issuer/network of the credit card) using an algorithm, wherein at least part of the credit card information may be changed and the changes may, in some cases, be made based on a predefined pattern or method. Credit card information may comprise numbers, names, expiration dates, security codes, and/or issuer information associated with the credit card. Additionally, one or more usage rules may be created and associated with the proxy credit card information, wherein the usage rules may define how the proxy credit card information may be used. Usage rules may comprise purchase amount limit, number of uses limit, frequency of use limit, time limit, and/or merchant specification. Additionally, usage rules may comprise a specification of (or limitation for) the type of merchant and/or type of goods bought, such as gas stations, groceries, or auto repairs, for example.

Turning now to FIG. 1, a communication system 100 is described. In an embodiment, the system 100 may comprise a mobile communication device 102. The mobile device 102 may comprise a radio transceiver 104, a secure element 106, a plurality of communication applications 108, a near field communication (NFC) transceiver 110, and an optional credit card application 111. The mobile device 102 may be configured to use the radio transceiver 104 to establish a wireless communication link with a base transceiver station (BTS) 112, and the base transceiver station 112 may provide communications connectivity of the device 102 to a network 114. The network 114 may comprise any combination of private and public networks. The base transceiver station 112 may also be known as a cell tower.

It is understood that the system 100 may comprise any number of mobile communication devices 102 and any number of base transceiver stations 112. The collectivity of base transceiver stations 112 may be said to comprise a radio access network, in that these base transceiver stations 112 may provide radio communication links to the mobile communication devices 102 to provide access to the network 114. The radio access network may be abstracted in different ways and may comprise, in addition to the base transceiver stations 112, servers and data stores such as home location registers (HLRs) or servers that implement the functionality of home location registers, visitor location registers (VLRs) or servers that implement the functionality of visitor location registers, base station controllers (BSCs), mobile switching centers (MSCs), and other network nodes that are specifically associated with providing wireless access and connectivity to the mobile communication devices 102.

The radio transceiver 104 may be in communication with the base transceiver station 112 using any of a variety of wireless communication protocols including a code division multiple access (CDMA) wireless communication protocol, a global system for mobile communication (GSM) wireless communication protocol, a long-term evolution (LTE) wireless communication protocol, a world-wide interoperability for microwave access (WiMAX) wireless communication protocol, or another wireless communication protocol. The device 102 may be any of a mobile phone, a personal digital assistant (PDA), a media player, a wireless enabled computer, a tablet, or other mobile communication device. In an embodiment, the mobile communication device 102 may have other components (not shown) such as a near field communication (NFC) radio transceiver, a wireless local area network (WLAN) radio transceiver, or other components.

The communication applications 108 may comprise a voice communication application, a data communication application, a web browser application, an email application, a short message system (SMS) or texting application, a multimedia message system (MMS) application, and other communication applications. The communication applications 108 may be standard communication applications that are delivered by an original equipment manufacturer (OEM) who assembles the mobile communication device 102. The communication applications 108 may be stored as firmware or software in a memory area of the mobile communication device 102. The communication applications 108 may expose application programming interfaces (APIs) accessible to other applications to provide wireless communication functionality to the other applications.

The secure element 106 of the mobile device 102 may be operable to store information (such as credit card information, loyalty card information, and/or coupons, for example) in a secure fashion, wherein the information may be accessed by a user of the mobile device. Additionally, a user may allow (or enable) one or more applications on the mobile device to access the information stored in the secure element 106, wherein the secure element 106 may be operable to store and/or execute applications. The secure element 106 may comprise a chip or chipset which may be installed or embedded on a mobile device 102 by a service provider and/or an original equipment manufacturer (OEM). The secure element 106 may comprise an environment in which application code and application data may be securely stored and administered and in which secure execution of applications may occur. The secure element 106 may provide security for transactions completed via a near field communication (NFC) enabled application 110, wherein personal information may be kept secure during the transaction.

The NFC transceiver 110 may be embedded in the mobile device 102 and enable the mobile device to communicate with other NFC-enabled devices. An NFC-enabled device may include point-of-sale (POS) terminals 130, for example, wherein the point-of-sale terminal 130 may comprise an NFC transceiver 132 as well. In an embodiment, the mobile device 102 may communicate purchase information to the point-of-sale terminal 130 via the NFC transceivers 110 and 132 during a transaction. The point-of-sale terminal 130 may be operable to communicate with a network 114, wherein the point-of-sale terminal may comprise a transceiver operable to allow communication via a base transceiver station 112 or alternatively may communicate with the network 114 via a wired connection.

In an embodiment, the credit card application 111 of the mobile device 102 may be stored and/or executed by the secure element 106. The credit card application 111 may be operable to access credit card information, wherein the credit card information may be stored in the secure element 106, and create proxy credit card information based on the original credit card information. Alternatively the credit card information may be stored in a cloud, wherein the cloud may comprise memory controlled by the network 114 or network server 116. The use of proxy credit card information for a transaction may allow for additionally security, particularly for online transactions. In an embodiment, the proxy credit card information may be generated based on the original credit card information using an algorithm or similar process. The credit card application 111 may be installed or embedded on a mobile device 102 by the user of the mobile device, a service provider, a credit card issuer, and/or an original equipment manufacturer (OEM). The credit card application 111 may also communicate with the issuer of the original credit card, wherein an issuer database 120 may store credit card information. In an embodiment, one or more usage rules may be created that are associated with the use of the proxy credit card information. Usage rules may comprise purchase amount limit, number of uses limit, frequency of use limit, time limit, and/or merchant specification.

In an embodiment, the proxy credit card information may be created using an algorithm based on the original credit card information, wherein the final proxy credit card number may satisfy Luhn's algorithm. In some embodiments, the proxy credit card number created by the application 111 may not satisfy Luhn's algorithm, wherein some payment systems may comprise a check to eliminate the use of false numbers. Therefore, the proxy credit card number may be altered to satisfy Luhn's algorithm before use in a transaction. Additionally, the proxy credit card information may contain some portions of the credit card number that may be unchanged from the original credit card information, for example a first four digits or a first six digits of a sixteen digit number of the original credit card number. This may allow for identification of the original credit card information by an issuer of the credit card, and may also allow for correct routing to the issuer and/or network associated with the original credit card. For example, one or more of the first six digits of the credit card number may remain unchanged, as those are typically the digits associated with the issuer and or network of the card. In some embodiments, the process of generating proxy credit card information may be repeated for use in multiple transactions, wherein the algorithm used to generate the proxy credit card information may change on a rotational basis. For example, a pattern may be used to generate consecutive proxy credit card numbers (or information) wherein the pattern may be known by both the application 111 on the mobile device 102 as well as the application 118 executed by the network server 116.

In an embodiment, a user may initiate a transaction, wherein the transaction may be completed on a mobile device 102, at a POS terminal 130, or on another device such as a computer, for example. The user may then open the credit card application 111, wherein the application 111 may access original credit card information from the secure element 106 and generate proxy credit card information based on the original credit card information. In an embodiment, the credit card application 111 may be operable to auto-fill the proxy credit card information into a transaction, eliminating the need for the user to type in the full proxy credit card information using the mobile device 102. Additionally, usage rules may be created and associated with the proxy credit card information, wherein the usage rules may be based on user input. For example, a user may specify a purchase amount limit for the proxy credit card information, wherein a purchase over the limit may be denied. Additionally, a user may specify a limit for the number of uses for the proxy credit card information, wherein any transactions exceeding the limit may be denied.

For example, a user may specify a maximum of two uses of the proxy credit card information, a maximum of four uses of the proxy credit card information, a maximum of six uses of the proxy credit card information, a maximum of twenty uses of the proxy credit card information, or some other relatively small maximum number of uses of the proxy card information. Also, a user may specify a maximum frequency of use for the proxy credit card information, such as monthly, annually, etc., where a usage of the proxy credit card information outside of the specified frequency may be denied. Additionally, a user may specify a specific merchant or business that may conduct a transaction using the proxy credit card information, wherein any use of the proxy credit card information at a different merchant or business may be denied. A user may also specify a time limit for use of the proxy credit card information, such as 2 hours, 6 hours, 24 hours, 2 days, for example, wherein after the time limit has past, the proxy credit card information may not be valid and may be denied. In an embodiment, a user may choose a merchant, input the name of a merchant, or may specify the merchant that first completes a transaction with the proxy credit card information.

It is understood that the user may invoke one or more methods of the credit card application 111 to generate the proxy credit card information and/or to define the usage rules described above. Additionally, the user may invoke the method or methods of the credit card application 111 again to generate a new proxy credit card information set that is new and/or different from the previous proxy credit card information but again is deterministically related to the original credit card number by the generation algorithm and/or to generate new usage rules. In an embodiment, when new proxy credit card information is generated, the previous proxy credit card information is deleted from the secure element 106. Alternatively, in an embodiment, when new proxy credit card information is generated, the previous proxy credit card information may remain stored and active in the secure element 106, still subject to the usage restrictions associated with that previous proxy credit card information. The credit card application 111 may provide an interface that allows a user to select one of a plurality of proxy credit card information sets stored in the secure element 106 to be active on the mobile device 102 at one time, for example in association with providing a personal identification number (PIN) or other secure token to qualify the selection. This behavior may promote a parent providing access of different children to different usage rules of different proxy credit card information sets or an employer providing access of different employees to different usage rules of different proxy credit card information sets. When a first child or employee is to use the mobile device 102 for payment transactions, the parent or employer may enter the PIN or other secure token and activate a first set of proxy credit card information; when a second child or employee is to use the mobile device 102 for payment transactions, the parent or employer may enter the PIN or other secure token and activate a second set of proxy credit card information.

The proxy credit card information as well as the associated usage rules may be communicated to the issuer of the credit card, wherein the issuer may associate the proxy credit card information with the original credit card information (and therefore the user of the original credit card information) and may also enforce the usage rules associated with the proxy credit card information. Alternatively, the credit card application 111 may only communicate an indication that proxy credit card information has been created, wherein a server 116 associated with the issuer may comprise a credit card application 118 similar to the credit card application 111 of the mobile device 102 operable to generate the same proxy credit card information as the credit card application 111. Additionally, default usage rules (or settings for the usage rules) may be used wherein the default usage rules may be known by the issuer server 116 and may not be communicated from the mobile device 102 to the network server 116.

FIG. 2 illustrates a method 200 according to an embodiment of the disclosure. The method 200 comprises initiating a transaction using a mobile device, at block 202, wherein the transaction may be completed in part by the mobile device. At block 204, the method comprises creating proxy credit card information using an application on the mobile device, wherein credit card information may comprise one or more of numbers, dates, codes, names, addresses, and/or issuer information associated with the credit card.

In an embodiment, the steps at blocks 204, 206 and 208 may proceed the initiation of a transaction at block 202. At block 210, the method may further comprise feeding the proxy credit card information into the payment transaction, wherein the payment transaction may comprise an NFC transaction, an online merchant transaction, or other similar transaction interface. In an embodiment, the proxy credit card information may be automatically fed into the payment transaction by the application on the mobile device. Alternatively, the proxy credit card information may be manually fed into the payment transaction by the user of the mobile device.

FIG. 3 illustrates a method 300 according to an embodiment of the disclosure. The method 300 may comprise initiating a transaction involving a device which may be separate from the mobile device, at block 302. At block 304, the method may comprise creating proxy credit card information using an application on the mobile device, wherein the proxy credit card information may be based on original credit card information stored in the mobile device. In an embodiment, the original credit card information may be stored in a secure element on the mobile device, and credit card information may comprise any numbers, dates, codes, names, addresses, and/or issuer information associated with the credit card. At block 306, the method may comprise creating at least one usage rule associated with the use of the proxy credit card information, wherein a usage rule may comprise a purchase amount limit, number of uses limit, frequency of use limit, time limit or merchant specification. At block 308, the method may comprise communicating the proxy credit card information and the at least one usage rule to an issuer of the credit card. In some embodiments, the above mentioned steps may be completed in a different order than described. For example, the initiation of a transaction at block 302 may occur after block 306 or 308. At block 310, the method may further comprise using the proxy credit card information to complete the transaction. In an embodiment, the transaction may be completed by a device separate from the mobile device, wherein the device may communicate with the issuer of the credit card to verify the information. In an embodiment, the issuer may verify the proxy credit card information after receiving the proxy information from the mobile device. In an alternative embodiment, the issuer may generate the proxy credit card information based on communication with the mobile device. In an embodiment, the device on which the transaction is completed may comprise a point of sale (POS) terminal and/or an online store or merchant, wherein completing the transaction may comprise communicating the proxy credit card information to the device via user input and/or near field communication (NFC).

FIG. 4 depicts the mobile device 400, which is operable for implementing aspects of the present disclosure, but the present disclosure should not be limited to these implementations. Though illustrated as a mobile phone, the mobile device 400 may take various forms including a wireless handset, a pager, a personal digital assistant (PDA), a gaming device, or a media player.

FIG. 6B illustrates an alternative software environment 620 that may be implemented by the DSP 502. The DSP 502 executes operating system software 628 (for example an operating system kernel) and an execution runtime 630. The DSP 502 executes applications 622 that may execute in the execution runtime 630 and may rely upon services provided by the application framework 624. Applications 622 and the application framework 624 may rely upon functionality provided via the libraries 626.

FIG. 7 illustrates a computer system 700 suitable for implementing one or more embodiments disclosed herein. The computer system 700 includes a processor 702 (which may be referred to as a central processor unit or CPU) that is in communication with memory devices including secondary storage 704, read only memory (ROM) 706, random access memory (RAM) 708, input/output (I/O) devices 710, and network connectivity devices 712. The processor 702 may be implemented as one or more CPU chips.

It is understood that by programming and/or loading executable instructions onto the computer system 700, at least one of the CPU 702, the RAM 708, and the ROM 706 are changed, transforming the computer system 700 in part into a particular machine or apparatus having the novel functionality taught by the present disclosure. It is fundamental to the electrical engineering and software engineering arts that functionality that can be implemented by loading executable software into a computer can be converted to a hardware implementation by well known design rules. Decisions between implementing a concept in software versus hardware typically hinge on considerations of stability of the design and numbers of units to be produced rather than any issues involved in translating from the software domain to the hardware domain. Generally, a design that is still subject to frequent change may be preferred to be implemented in software, because re-spinning a hardware implementation is more expensive than re-spinning a software design. Generally, a design that is stable that will be produced in large volume may be preferred to be implemented in hardware, for example in an application specific integrated circuit (ASIC), because for large production runs the hardware implementation may be less expensive than the software implementation. Often a design may be developed and tested in a software form and later transformed, by well known design rules, to an equivalent hardware implementation in an application specific integrated circuit that hardwires the instructions of the software. In the same manner as a machine controlled by a new ASIC is a particular machine or apparatus, likewise a computer that has been programmed and/or loaded with executable instructions may be viewed as a particular machine or apparatus.

The secondary storage 704 is typically comprised of one or more disk drives or tape drives and is used for non-volatile storage of data and as an over-flow data storage device if RAM 708 is not large enough to hold all working data. Secondary storage 704 may be used to store programs which are loaded into RAM 708 when such programs are selected for execution. The ROM 706 is used to store instructions and perhaps data which are read during program execution. ROM 706 is a non-volatile memory device which typically has a small memory capacity relative to the larger memory capacity of secondary storage 704. The RAM 708 is used to store volatile data and perhaps to store instructions. Access to both ROM 706 and RAM 708 is typically faster than to secondary storage 704. The secondary storage 704, the RAM 708, and/or the ROM 706 may be referred to in some contexts as computer readable storage media and/or non-transitory computer readable media.

I/O devices 710 may include printers, video monitors, liquid crystal displays (LCDs), touch screen displays, keyboards, keypads, switches, dials, mice, track balls, voice recognizers, card readers, paper tape readers, or other well-known input devices.
